1. An aerodynamic flow control device comprising a compact arrangement of an array of a plurality of discrete fluidic actuators having non-interconnected feedback channels located on a substrate wherein each of said plurality of said fluidic actuators comprises an input port and an exit port wherein each of said actuators is capable of producing at said exit port an oscillating or sweeping jet either in-plane or perpendicular to the plane of the fluid flow inside said actuator further comprising a common extension chamber extending from the exit ports of said plurality of fluidic actuators thereby directing the exiting flow in a specific or predetermined direction.
